Citizen Eco-Drive Super Titanium watch, titanium, AW1240-57E
Citizen Eco-Drive Super Titanium is a titanium watch with a black vertically striped dial and a sapphire crystal
The black, vertically striped dial and silver-gray titanium make this Citizen Eco-Drive watch a understated and clear men's watch. The hour markers are baton-shaped, and there is a date display at three o'clock. The round case is 42 mm wide and 10 mm thick, and a sapphire crystal protects the dial. The luminous coating makes it easier to read the time in the dark.
The case and bracelet are made of Super Titanium, which is 40% lighter than steel and 5 times harder than normal titanium. The bracelet is 20 mm wide and fits wrists of 160–210 mm. The watch runs on light, so the battery does not need to be replaced. The year 2026 marks the 50th anniversary of Eco-Drive technology. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but the watch is not suitable for scuba diving.
